' consists in a pump of the flange 0 is an outwardly extending GEARING.

To all whom it may concern Be it known that I, FRANK citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful" Improvements in Gearing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

My present invention relates to air pumps for use in connection with automobiles and of this characteradapted to be connected with the frame of the motor or other parts of the automobile and to be actuated when desired by said motor.

In the accompanying drawings, I have shown the best form in which I have contemplated embodying my said invention and the same. is disclosed in thefollowing de- E. T EN EYoK,

scription and claims.

pump.

a is themotor shaft from which the pump is actuated.

b is the pump shaft for actuating the piston of the pump. Thepiston is not shown as the construction of the same and the devices for actuating it maybe of the character preferred by the constructor.

In one form of clutch construction, upon the shaft 12 is secured the sleeve 0 provided with the parts forming one of the clutch members. These parts consist of the 'narrow flange c at the outer end of the sleeve 0 extending the greater portion ,of the distance around the sleeve. Between the ends projection c of greater thickness than the .fiange, with a space 0 between each end of the flange and the projection. Upon the shaft (1 is the'gear a secured thereto. and

' moving with said shaft.

Specification of Letters Patent.

' f is connected readily brought into Patented Apr. 6, 1915..

Application filed July co, 1am. Serial No. 712,335.

Upon the inner portion of the sleeve 0 is loosely mounted the gear d. This gear is provided on its outer sidewith the projec tion ol and the hub of the same extending inwardly is provided with the. groove 0Z The projection d is of a size to engage the spaces 0 on either side of the projection.

In the other form of clutchwhich is illustrated in Fig. 6 the bearing of the shaft 1) is provided with the outwardly extending sleeve b upon which the wheel (1 of the construction heretofore described, is mounted. To the outer end of the shaft is rigidly secured the clutch member comprising a collar-having the flange c and The action in this case is the same as that heretofore described, except that when the clutch members are in engagement the wheel revolves upon the sleeve b.

The outlet from the pump cylinder F is at the upper end of the same and is, as usual, provided with a valve permitting the compressed air to escape from the cylinder but preventing the return of the same. This outlet is provided with a nozzle 7 to which a conducting pipemaybe attached. A pipe with the nozzle which extends downwardly pressure cylinder G. Within this cylinder is a piston g. To this piston or an extension therefrom, is connected an arm 9 having a forked end adapted to engage the groove 0& in the hub of the gear (2.

In order toenable the gears a and d to be mesh with each other every alternate tooth is cut away on the side of'the gear normally nearest the other for about one third of its length, as seen at a and d.

The operation of the device is as follows: A pipe for conducting compressed air from the air pump to atire to be inflated, is connected at one end to the nozzle 7 and is provided at the other end with a suitable con nection for engaging the tire valve tube. This connection is provided with the usual means for engaging the tire valve stem in the valve, tube and opening the same. As soon as the said connecting deviceis secured in place on the end of the valve tube, thereby opening the tire valve the compressed air already in the tire rushes o t through the tube into the nozzle f and the cethrough projection 0 and connects with the the pipe f to the pressure cylinder G, and moves the piston g thereof outwardly (to the right in Figs. 1 and 2). The arm 9 moves the gear d toward the gear a. The full length teeth of one enter the spaces between the full length teeth of the other and the gear-d is put in motion. This gear'being loose upon the sleeve 0 revolves freely without actuating the shaft 6. When the full length teeth of the gears a and d are brought into mesh the projection (13 will be forced into contact with the flange c of the sleeve 0 and thereafter into contact with the projection 0 WVhen the projections d and c are engaged the shaft 6 will be put in motion, the sleeve 0 moving with the gear 03. The projection 03 will then be opposite or in line with a space 0 and the pressure of the piston g will force the projection into the space, completing the clutch movement.

In many cases where clutches are employed the engagement of the projections d and 0 would form -a sufficient connection between the parts, but as the small amount of air not discharged from the cylinder and the weight of the piston would tend to accelerate the movementv on the downward stroke of the piston, it is necessary that the two parts of the clutch should secure a rigid connection in order to provide against back-lash and the noise and jar on a'reengagement of the parts.

A space 0 is provided on each side of the projection c to enable the pump to be used" in a greater number of positions, and the pump to be used when run in either direction.

The specific form of clutch mechanism herein shown and described is not specifically claimed herein as it forms the subjectmatter of a divisional application filed by me on the 25 day of Aug, 1913.

What I claim and desire to secure by Letters Patent is Thecombination with a driving shaft, of

a pump provided with an actuating shaft, a driving gear fixed on said driving shaft, a driven gear normally out of alinement with the driving gear, loosely mounted concen- -between said lug and adjacent portions of the part provided with said arresting face, a lug secured to said movable gear constructed to fit said locking recess and prevent back-lash, and adapted to be arrested by said arresting face, when said gears are in mesh and said clutch lug on the movable gear is in position to engage the first mentioned clutch lug, an actuating cylinder and pistonfoperative connections between said actuating piston and the movable gear for actuating the same yieldirigly, and a connection for pressure fluid between the pump back pressure to the pump cylinder, to connect the pump shaft and the driving shaft, and-hold the connected arts in operative position continuously While the pump is in operation. k

In testimony whereof I afiix my s1gnature, in the presence of two witnesses.
